'DE'EIQUETABL E'IM AND MEANS EOE FASTENING SAME.

Application filed m 28,

p This invention relates generally to auto: m bile wheels and more particularly to the demountable tire carrying rim and the means for fastening said demountable rim upon the ,5 wheel bodyand providing a driving connecwheelbody. lhe

tion betwee-n said rim and object of the invention is to simplify the rim fastening means and at the same time provide a driving connection between the rim 1 and wheel body thereby eliminating certain parts heretofore employed and thereby elimi natingi' a defin'te amount- 01" weight; and at the same time reducing the cost of manufacture. A still further object'is to provide a, combined fastening and driving means which shall be exceedingly simple, easy to operate, and one which will tend toward greater ac: curacy in positioning the rim'upon the wheel. hody both as to concentricity and also the arrangement of a rim a true wheel plane.

With these yarious obj ects' in view, the invention consistsin the novel features of construction and in the manner of combining and arranging them, all of which will be fully described hereinatterand set forth in the appended claims. In the drawings forming a part of this specification Fig. 1 isa side elevation of a wheel having a demountable tire carryingrimcOnstructed and fastened in accordan'ce with my invention; Fi 2 is a side elevation ofthe tirecarrying rim removed from the wheel; 3 isa detail sectional view on the line 3,3 of Fig. 1; Fig. 4 is a, detailsectional view on the line 4+4: of 1,: Fig. 5 is a fragmentary. plan view; and Fig.1, 6 is '-detail perspective view of the p ..q., L In c yin 9 1s y e tion I p oy a wheel body preferably composed of a plual ty e i d e po es A a d a et metal fe1' y ..Q J ed r fmgB, an te fiiied rim being preferably 0t thechannel type as shown, although will loe' understood that the invefition b n be used'u'pon the ordinary telly bandiappliedi tol'a wooden telly. when the fixed rimor telly is of sheet metal and of the channel type, l preterj to make the. front leg thereof slightly horter than the rear leg in order to facilitate themounting and de-mountingot the rim thereon. The demountable tire carrying rim 0 may be either straight, side orwclincherand the base thereof is formed with an inwardly projecting bead or rib D adjacent the front side and this inwardly projecting bead or rib can be solid as shown 1921.

and constituting a part or a hot rolle d section or it canbe in the form of an inrolled bead rolled inwardly from the base proper. This inwardly projecting rib or bead is adapted to Contact with the front leg of the telly or fixed 1'] m when the demountable rim is-securely fastened upon the fixed rim or telly while the rear side of the base of the demountable rim contacts with the rear leg of the fixed rim or felly. v i Forthe purpose of fastening the demountable tire carrying rimupon the fixed rimordelly and at the same time providing a driving connection between the demountable rim and wheel body, I employ a number of cl amps each comprising an apertu'red portion E and a portion F substantially at right anp les to, the apertured portion E and which is adapted to fit between the fixed and demountable rims in the following,1nanner2'The inwardly pro ecting rib or bead D is recessed or cut away at definite intervals as indicated atD ,and the rearwardly projecting portion F of the clamp is adapted to fit into saidnotch orrecess and the shouldered portions upon opposite sides of the rearwardlyv projecting portion F contact with the front faces of the adjacent portions of said rib or bead. When the clamp is thus inserted between the fixed and demountablerims the, aperture in the member E will receive the front end of the ,transversebolt H therethrough anda nut I I screwed upon'the end of said bolt will force the clamp rearwardly and, the shoulders G contacting with the rib or bead will force the tire carrying rim to the true plane. The member vF is-sliethtly tapered as shownat F. tofacilitate theintroduction of the clamp between the telly and rim andthe outer portion F? thereot as a clamp, the clamp asa wholebeing drawn up tight by means of a nut andrbeinfr, forced into contact with both the fixedand demountable rims it engages thenotched or recessed portion of the demountable rim and provid es a driving connection'between the bolt and demountable rim and at the same time the shoulders G contacting, with the rib or bead force the demountable rim rearwardly and hold the same in place upon'the wheel body when the nut has been properly tightened, It will be noted that the rear, end of the nut is taperedto fit theconnterbored opening in the nember E thereby'providing a locking connection between the nut and clamp;

is made flat so that the device acts It will be noted that the portion E of the clamp which extends radially inward is spaced from the fixed rim. The result is that the clamp does not fulcrum upon the fixed rim and the full pull of the bolt exerted by V the nut I on the clamp is transmitted to the I claim is I 1. The combination with a channeled fixed rim, of a demountable tire carrying rim having an inwardly projecting bead adapted to contact with the front leg of the fixed rim, said head being notched or recessed at definite points, and clamps carried by the fixed rim and having eacha rearwardly projecting portion adapted to fit between the fixed and demountable rims when occupying the notched or recessed portion of the inwardly projecting bead, and laterally. projecting shoulders adapted to engage the adjacent portions of the inwardly projecting bead,

said. clamps having radial inwardly extend.

ing portions spaced from the fixed rim and removed from hearing contact therewith at all points.

2. The combination with a fixed rim of a demountable the carrying rim arranged thereon, said demountable rim having an inwardly projecting bead, said head being notched or recessed at definite points, clamps carried by thefixed rim and having each a rearwardly projecting portion adapted to fit between the' fixed and demounta-ble rims andoccupy one of the notched or recessed portions of the inwardly projecting bead, saidclamps having oppositely disposed laterally projecting shoulders adapted to engage the adjacent portions of the inwardly projecting bead and radial inwardly extending portions spaced from the fixed rim and removedfrom bearing contact therewith at all 7 points. 1

crying bolts, of a demountable tire carrying rim arranged upon the fixed rim and having an inwardly projecting bead, said bead be ing recessed or notched at definite intervals, and clamps each having one member apertured and adapted to fit upon one-of the bolts carried by the fixed "rim, said member being removed from hearing contact with the fixed rim at all points,and another member adapted to fit between the fixed and demountable rims and occupy a notch or recess in the inwardly projecting bead. each of said clamps havinglaterally projecting shoulders upon opposite sides'of said last named member, adapted to engage the inwardly projecting rib or bead,,and nuts for securing the clamps, each of said nuts engaging the apertured member of one of said clamps, whereby. the full pull of the nut is transmitted by the clamp to thedemountable rim.
